Question

ANSWER ANY TWO OF THE FOLLOWING. EACE
1. a) For the molecule CH3CH2CH2OH
i) Identify functional group.
ii) Write the bond line formula.
iii) Write the succeeding homologue.
b) Explain inductive effect with a suitable example​

Answer 1

Answer:

1a)i.alcohol

ii)The chemical formula of 1-Propanol is CH3CH2CH2OH. It is a colourless liquid which is also called as 1- propylalcohol, propan-1-ol. 1 propyl-alcoholl is known as an isomer of 2-propylalcohol.

iii)The repeating unit can be the length of the carbon chain. That means in the given compound, the repeating unit is . So, the homologue of propanal is butanal.

b)it is defined as the change in the polarization of a covalent bond due to the presence of adjacent bonded atoms or groups in the molecule. ... Atoms or groups which draw electrons away from a carbon atom are said to have a -l effect. Example: -NO2 - -1, -Br, -OH, C6H5 etc.
